About this package

A client and server SSH library.

Russh

Low-level Tokio SSH2 client and server implementation.

Examples: simple client, interactive PTY client, server, SFTP client, SFTP server.

This is a fork of Thrussh by Pierre-Étienne Meunier.

Safety

• deny(clippy::unwrap_used)
• deny(clippy::expect_used)
• deny(clippy::indexing_slicing)
• deny(clippy::panic)
• Exceptions are checked manually

Panics

• When the Rust allocator fails to allocate memory during a CryptoVec being resized.
• When mlock/munlock fails to protect sensitive data in memory.

Unsafe code

• cryptovec uses unsafe for faster copying, initialization and binding to native API.

Ecosystem

• russh-sftp - server-side and client-side SFTP subsystem support for russh - see russh/examples/sftp_server.rs or russh/examples/sftp_client.rs.
• async-ssh2-tokio - simple high-level API for running commands over SSH.

Adopters

• HexPatch - A binary patcher and editor written in Rust with terminal user interface (TUI).
  • Uses russh::client and russh_sftp::client to allow remote editing of files.
• kartoffels - A game where you're given a potato and your job is to implement a firmware for it
  • Uses russh:server to deliver the game, using ratatui as the rendering engine.
• kty - The terminal for Kubernetes.
  • Uses russh::server to deliver the ratatui based TUI and russh_sftp::server to provide scp based file management.
• lapdev - Self-Hosted Remote Dev Environment
  • Uses russh::server to construct a proxy into your development environment.
• medusa - A fast and secure multi protocol honeypot.
  • Uses russh::server to be the basis of the honyepot.
• rebels-in-the-sky - P2P terminal game about spacepirates playing basketball across the galaxy
  • Uses russh::server to deliver the game, using ratatui as the rendering engine.
• warpgate - Smart SSH, HTTPS and MySQL bastion that requires no additional client-side software
  • Uses russh::server in addition to russh::client as part of the smart SSH functionality.
• Devolutions Gateway - Establish a secure entry point for internal or external segmented networks that require authorized just-in-time (JIT) access.
  • Uses russh::client for the web-based SSH client of the standalone web application.
